The injunction bans Mind Candy from “promoting, advertising, selling, distributing or otherwise making available to the public” any work involving Lady Goo Goo.

It also prevented Mind Candy from doing the same with “any musical work or video which purports to be performed by a character by the name of Lady Goo Goo, or which otherwise uses the name Lady Goo Goo or any variant thereon”.

Children visiting the website can adopt and care for a pet monster, and solve puzzles earning them reward points called rox.

Mind Candy said in a statement the ruling was ‘a huge disappointment’ and that “it’s pretty obvious that kids will be able to tell the difference between the two characters”.
